Anchoring the skyline in Ningbo Eastern New City, Zhejiang province, the Ningbo Bank of China tower is the newest landmark in the city’s financial district. Surrounded by a landscaped public plaza, the 50-story tower serves as headquarters of one of the nation’s fastest growing banks and stands as a gathering place for the neighborhood in the heart of the financial district.
Clad in a sweeping curtain of glass, the tower integrates a porous metal diagrid canopy to cap a pedestrian-level podium and shelter, with a rooftop garden. Inside the podium, an open, three-story lobby provides full-service banking and houses a private employee cafeteria on the fourth floor.
Each floor of the tower rotates one degree and steps in 100mm around the central core to create a seamless, twisting form from base to crown. All floors utilize 48 perimeter mini-columns draped vertically to avoid structural torque and provide an identical framework for flexible, column-free lease spaces.
Ample natural light permeates the interiors, which provide shifting vantage points of the city, mountains and sea, and a public open-air crown provides sweeping panoramic views, 246 meters above street level.
The tower also features a comprehensive sustainability scheme, including smart appliances, recycled building materials, individual controls for lighting and thermal systems, improved insulation, and a façade punctuated with translucent fins between high-performance glass panels, mitigating solar gain.
A modern embodiment of Ningbo’s history of banking, the new Bank of China reinforces the company’s reputation as a leading institution in China.
Ningbo is one of the oldest cities in China, and significant population growth by the late 20th century exponentially accelerated urbanization in Ningbo, driving local government to announce Eastern New City in 2002, adding roughly 16 square kilometers of urban area to Ningbo.
Plans for Eastern New City emphasized the use of modern technology and traditional environmental conservation methods to reduce the environmental impact of rapid urban expansion. With the new “eco city” as a foundation, the Ningbo Bank of China tower forms a sustainable landmark and community gathering place in the city’s official financial district.
Translucent vertical fins animate the facade and infuse interior spaces with daylight, while mitigating solar gain and glare. Responsive and individual controls support lighting and thermal systems, while high-efficiency equipment, smart appliances, and improved building insulation support the overall energy efficiency of the building.
Community connectivity is established through on-site bicycle storage, public transportation access, and a pedestrian-level podium with an expansive canopy clad in perforated metal, providing shelter and connection to an adjacent landscaped public plaza. As part of the site master plan, the plaza links to the nearby Fenghua River, creating new pathways and encouraging foot traffic through the heart of the financial district.
By incorporating thoughtful sustainable strategies, including strong community connectivity, locally sourced and recycled materials, high efficiency equipment, daylighting, and improved insulation, the Ningbo Bank of China tower effectively and efficiently strengthens the district’s eco-conscious master plan.
The tower utilizes vertical solar shading devices that accent the form of the building, reduce the direct solar gains to provide an energy reduction of approximately 3%. The podium utilizes a perforated metal panel system that provides significant solar shading and reduces solar gains. High-efficiency mechanical equipment and individual control of lighting, natural ventilation and thermal comfort systems allow for reduced energy consumption.
The site is in the Eastern New City along a fully landscaped public park. Multiple planned public transportation stations including subway lines and a bus terminal are located within blocks of the site. Limited below-grade parking is provided in conjunction with a basement shared with adjacent sites. Dedicated bicycle parking in secured and directly accessed spaces is also provided below grade.
Water use reduction strategies include water efficient fixtures for an approximate 20 percent reduction compared to base line. Permeable paving is used on site to ground water retention.
Construction utilized locally sourced and recycled materials, as well as post-consumer recycled content in structural steel. The building massing is defined by a draping geometry around a vertical core to provide consistent floor plates and reduce structural torque, ultimately minimizing construction materials.
